Dimensions

Bronze and brass hollow rods are executed in accordance with BN-89/0825-01 and they are of the following dimensions:

- 30 to 200 mm diameter with graduation of diameter and wall thickness every 1 mm.

The minimum thickness of the hollow rod’s wall is 10% of the external diameter.

Profiles (rectangles, solid and hollow squares, e.g.) – dimensions, shapes and others specific requirements are available upon agreement.

Length of the product: 2m (regular) or others – according to customer demand



Properties

Hollow rods and profiles are manufactured according to BN-89/0825-01 or according to agreed conditions. In comparison with sand castings, they are characterized by higher resistance and technological properties (for example, their leaktightness is definitely better).
